The Net Force is equal to the mass of the Object multiplied by the amount of Acceleration. Therefore, this creates an equation which looks like this:
F = Mass * Acceleration
F = 2.569 kg * 4.65 m/s
F = 11.95 N
Hopes this helps!
Answer is A, an iron nail rusting. Rusting is know as a chemical change. Iron and oxygen atoms react with each other to create a chemical reaction. This creates an new substance called iron oxide.
Answer:
1. the bottom layer
2. aqueous HCI
3. the top layer
4.aqueous NaOH
5. mostly in the diethyl ether layer
Explanation:
Pure dimethylformamide is considerably more polar than hexane hence thee two solutions will form two phases with the pure dimethylformamide as the bottom layer.
If we want to extract aniline from chloroform, HCl must be added in order to give a salt that can be extracted into the aqueous layer.
For a mixture of methylene chloride and diethyl ether, the diethyl ether layer will be found as the top layer since it is considerably less polar than methylene chloride.
Benzyl alcohol can be extracted from a solution of chloroform by adding NaOH and extracting it into an aqueous layer.
A large partition coefficient for the extraction of naphthalene into diethyl ether from water means that naphthalene will be found mostly in the diethyl ether layer.
2 qualitative: she measures the cupcakes and finds the difference and she estimated that she would get bigger cupcakes if she put more eggs quantitive: she sees that the cupcake with 3 eggs is 0.25 centimeters taller than the cupcake with 2 eggs and she did not get any more extra cupcake even though the cupcake with 3 eggs was taller
Explanation:
All resources used in making all products can be traced to their natural origin. What differentiates a natural product from a synthetic one is the level of processing that goes into making synthetic products.
- For example, a synthetic product such as plastic is actually derived from natural product.
- Instead of using the sap of rubber plants for making this product, scientists engineered a way to produce plastics from petroleum products which are derived from crude oil.
- Most synthetic products are merely products of alternate source of manufacturing which are well engineered.
